нужен or нужно?
"кто вам нужен?" "Кого вам нужно?"
I've seen both sentences but I don't know why in the first sentence it's нужен and in the second one it's нужно, could you help me figure out how to determine if I should use нужен or нужно in sentences like those listed above

Thank you for attention

Answer

I think «кого Вам нужно?» is a vernacular, people still sometimes say like that, but to me «кто Вам нужен?» sounds much better. I'm suggesting you to use «кто Вам нужен?» only and forget the second option.

Answer

Кто is supposed to be male, that's why нужен. Кто is the subject.

There is no subject in the second sentence, it is similar to Мне холодно, На улице темно. That's why нужно (neutral). 
One says, Кого вам нужно? Что (/чего) вам нужно?

Answer

Ok, thank you:)

Answer

here is all correct))

кто = нужен (he/she)

кого =  нужно (it)

but in russian we use "кто вам нужен?" doesn't metter of sex))  phrase  "кого вам нужно?" most of the time sounds ungrammatical))
